Polyurethane Vibration Damping Pad

Polyurethane (PU) elastomers are copolymers composed of soft segments and hard segments. The main components of the soft segments are polyester or polyether oligomer polyols, while the hard segments mainly consist of the reaction products of polyisocyanat

Polyurethane Vibration Damping Pad

● Closed-cell polyurethane
● Point support, line support, surface support
● Low water absorption
● Surface static stiffness up to 12 N/mm²
● Extremely high dynamic efficiency
● Excellent mechanical properties
● Outstand

Main features and advantages

Polyurethane shock absorber pads - application in the field of rail transit

During the operation of urban rail transit, impact vibrations are generated between train wheels and rails, which are transmitted through sleepers and ballast to tunnel or bridge foundations, and further transmitted to and affect surrounding buildings and sensitive equipment. The affected building structures can amplify the vibration excitation generated by locomotives, thereby causing damage to the building structure, such as settlement or cracks. This type of vibration (especially low-frequency vibration) not only interferes with and impacts the operation of residential houses, schools, hospitals, and other environments along the subway line, but may also adversely affect the quality and productivity of their equipment. Long-term exposure to these vibrations and the secondary airborne noise they generate can easily harm comfort and human health. Vibratec® polyurethane elastic pads can be applied both to trackbed vibration isolation under compressive and shear loads and to vibration isolation for industrial equipment. Based on engineering characteristics and vibration reduction requirements, Vibrotec provides polyurethane vibration-damping pad systems in discrete supports, linear supports, and fully laid supports. Vibrotec engineers offer effective vibration reduction solutions, detailed installation guidance, and on-site training for each project application. To ensure smooth installation and a high level of vibration reduction, our services include the following:
